OTTAWA — Another recall has been issued involving meat from the Maple Leaf Foods packing plant in Toronto linked to a listeriosis outbreak that has killed at least 13 people.

The Canadian Food Inspection Agency is warning the public not to serve or consume Canex Maple Leaf Bologna with best before dates up to and including Oct. 10.

The CFIA says the bologna, a product recalled earlier by Maple Leaf, may be contaminated with Listeria monocytogenes.

The affected bologna was sold in vacuum packed packages of various weights at Canex Retail Supermarket in Happy Valley-Goose Bay, N.L.

To date, there have been 38 confirmed cases of listeriosis.

Prime Minister Stephen Harper has promised to launch a broad, independent investigation into the listeriosis outbreak that has resulted in the recall of more than 200 products.
